WElGHlNG AND FILLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 608,117, dated July 26,1898.

Application filed September 9,1897. Serial No. 651,100. (No model.)

To (tZZ whom it may concern:

Be it known that I, JOSEPH J. GOODLETT, of Memphis, in the county ofShelby and State of Tennessee, have invented a new and ImprovedlVeighing and Filling Apparatus, of which the following is aspecification.

The invention is an apparatus for filling various forms of receptacleswith liquid of any kind, and it is adapted to deliver a predeterminedquantity of the same and to cut off the delivery automatically.

The apparatus includes as its chief elements a weighing-scale upon whichthe liquid-receptacles are placed to be filled, a filler proper, whichis provided with automatic valve and trip mechanism for controlling theflow and delivery of liquid, and an electrical switch and circuit andcertain cooperating adjunctivc devices for actuating the said tripmechanism when the weighti. 6., the volnine-of the liquid delivered intoa receptacle reaches the predetermined limit.

The apparatus is illustrated in the accompanying drawings andhereinafter described with the necessary detail.

In said drawings, (two sheets,) Figure 1 is a front perspective view ofmy improved apparatus. Figs. 2 and 3 are detail views of the automaticswitch. Fig. 4, Sheet 2, is a side view of a portion of the apparatus.Fig. 5 is an enlarged vertical section of the adjustable post forsupporting the gooseneck discharge-tube and its attachments, part beingbroken away. Fig. 6 is a diagrammatic view of the electrical circuits.Fig. 7 is a sectional view showing a modification in the arrangement ofthe magnets.

Two platform-scales are arranged side by side on the same rectangularbase-plate A, which is provided centrally with two spiritlevels 1 2,arran ed at right angles to each other, and also with levelin gscrews 3,which pass through threaded holes in the corners of the plate andthrough a small metal plate at, that is secured to the under side ofthelat ter. Milled jam-nuts 5 are applied to the screws 3, which havewings to facilitate their manual manipulation.

Two posts or standards 13 rise from the rear side of the base-plate Aandsupport horizontal beams Z upon each of which a pivoted compound scalebeam or lever 7 is secured,

as shown. These scale-beams 7 are connected with the respectiveplatforms 8, as usual in platform-scales.

At a pointintermediate of and equidistant from the standards 13 islocated a vertical post 0, which is composed of two tubular parts, theupper one 9 fitting loosely in the lower or base part 10 and being heldin any required vertical adjustment by means of a clamp-screw 11, thatpasses through the said base part 10, as shown. To the upper end of theslidable part 9 are pivoted at opposite points two right-angular levers12 and 13, whose longer arms extend laterally and serve alternately asrests or supports for the goose neck or filler proper, D, when teeapparatus is in use. The shorter vertical arms of said levers 12 and 13bear upon the opposite ends of a short bar or red it, which passesthrough a transverse hole in the part 9 of post 0 and is free to slidefreely therein. This rod 1i being of greater length than the diameter ofsaid part 9, the vertical lever-arms cannot both be in contact with thepost 0 at the same time nor with the electrical switches in the form ofpush-buttons 15 and 16, which are set in transverse sockets or openingsin said part 9 and from which two sets of conductors 17 and 18 extenddown within the post C and laterally through the base of the same tobind ing-screws l9 and 20 and thence to the magnets 25. Wires 21 and 22also extend from buttons 15 16 to the same binding-screws 19 and 20 andthence (see Fig. 0) to the switches 23 and 2 and the battery. Themagnets 25 are suspended, Fig. 4, from a rigid inclined arm 26, which isattached to the handle 27 ofthe gooseneck D. The switches 23 and 2d areeach composed of a lever 28, pivoted at one end, and two contactplates29 and all of which are arranged in a box 31, secured upon a beam Z).Two binding-screws 32 connect the conductors 21 and 22, respectively,with these contact-plates 29 and 30.

The free end of the switch-lever 28, which projects from the box 81, isloosely connected by a link S-i with the short arm of the scalebeam 7,and the length of said link is so proportioned that when the scale-beam7 tilts the switch-lever 28 is thrown down and engages thecontact-plates 29 30, thus closing the circuit through the magnets 25,whereby the hit ter are energized and caused to attract the armature 35,forming an attachment of the valve mechanism of the filler, so that theflow of liquid through the same is out off or arrested. The filler D isin the main similar to that which forms the subject of my reissuedPatent No. 11,600, but more closely resembles the filler for which Ihave filed an application, Serial No. 628,850, dated March 23, 1807. Thetubular body 36 of the same has a bent discharge end and is jointed at37 to a part which is adapted for connection with a flexible or otherpipe (not shown) that leads to a tank or other source of liquid-supply.The valve 38 within the tube or gooseneck 36 is hinged and held normallyclosed by a spring 39 and is opened by a lever 40, affixed to its axis41 and ext-ending forward over the gooseneck-handle 27, where it isadapted to engage a trip device 42, that is pivoted to a rigid bracket43. Said device 42 is adapted to engage the valve-lever 40, and thushold the valve 38 open, being itself adapted to engage the pivoted lever44, carrying the aforesaid armature 35.

It will now be readily understood 110w the apparatus operates. Areceptacle to be filled with liquor or other liquid is set on one of theplatforms 8 and the pea of the upper member of the scale-beam 7 adjustedto balance the platform and thus indicate the tare, after which the peaon the other or lower member of the beam 7 is set at the weight of theliquid it is desired to deliver into said receptacle. The filler D isthen swung laterally from one of the angular levers-say 12-- and hung onthe other one, 13,which is nearest the platform supporting thereceptacle. Thus such lever 13 is depressed and its shorter arm broughtinto engagement with the pushbutton 16 on the adjacent side of the post9 and the other lever 12 held out of contact with the oppositepush-button 15. The valve-lever 40 is engaged with device 42 and thelatter by the lever 44. Liquid is then allowed to fiow, and when thevolume delivered into the receptacle equals the weight required thescale-beam 7 will be tilted and the switch-lever 28 depressed andengaged with plates 29 30, thus closing the circuit through the magnets25,which attract the trip-lever 44 and cause it to release the device42, which in turn releases the valve-lever 40, so that the valve 38closes and cuts off the flow of liquid. While this operation has beengoing on, time has been afforded for placing another receptacle 011 theother platform and adjusting the weight on the connected scale-beam asrequired. Then the filler D is shifted manually from the lever 13 backand rested on the opposite lever 12, as before,when, the electricalcircuit being again open, the filling operation is repeated.

As shown in Fig. 7, the magnets 25" may be arranged in a socket orrecess adjacent to the handle 27 a of the gooseneck, and in such casethe lever 44" and armature 35 are arranged over instead of under themagnets, as shown.
